Legal paperwork is all done electronically now. No need to visit some law office.If the individual lawyers have passed the WA bar exam, yes, quite true. Not sure how many Boise Cordell & Cordell lawyers would bother, being that Boise is six hours from the nearest populated area in WA. One would think the firm would open an office in WA somewhere instead.
Provided they have lawyers on staff qualified to practice law in Washington State, Idaho, or Kansas, all those states are in play.
